Really depends on the details. <br>
<br>
I've got a lot of equipment on Mountain Tops. <br>
A lot of them are the KPC3+, and they do just run. I've had one
that failed, but I suspect Lightning was the root cause of it's
problems. Several have been in place 15 years now. Oh, did just
remember one failure I fixed last summer, the actual plastic of the
on/off switch apparently dried out enough that the switch failed and
would no longer latch on (would power it if you held the switch).
Dab of solder solved that problem. <br>
<br>
For solar powered sites, I have a few that were KPC3+ and assorted
radios, but I eventually standardized on the Argent data T3-301,
which sadly is no longer available. It was the TNC and Radio in a
nice sized package. That with a solar controller and 17AH Battery
all fit in a 8x8x4" Electrical box. <br>
<br>
For the question about remote control, both the KPC3+, and the
T3-301 allowed changes remotely. Which was handy since several of
my sites are 12,000 feet or higher, and a couple are a significant
hike in. <br>
<br>
The other unit I've used a couple of and have been pretty happy
with, is the unit from Poland, the Microsat WX3in1 Mini. It's an
Igate that has the Ethernet interface built in and has a web
interface for the settings so can be programmed remotely. I've had
one of those in service for a couple of years now as an Igate and
haven't needed to touch it. Depending on exchange rates it's a
very reasonable priced unit, I think HRO even carries them now.
I've got a portable unit built up in an old GR300 cabinet with the
handle on top, that has a GM300, and one of those units, that anyone
could plug in the Ethernet cable, put out a mag mount antenna, and
plug it into AC and it would be up and running. <br>
<br>
my .02 worth. <br>

<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m looking for advice on current offering
for a robust, field-deployable digipeater TNC/modem.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Over the years my go-to device has been the
KPC-3+, mainly because when I started out with APRS the
sound-modem stuff was rubbish and not easily deployed in the
field without needing to be tweaked / set up each time. The
KPC-3+ is bomb-proof, out-performs most other hardware, low
power and just works (save for the known buffer/timing issues,
but they were solved in v9.1). I’ve never had one fail in 25
years (and I’ve had wide-area event systems deployed with a
dozen of them spread around the hills!).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The world has moved on and sound-modem
stuff is now very good, so looking at what options there are
for something that has multi-functionality - i.e. can be used
at a centre or in a mobile for situation awareness, perhaps
over LAN/Wi-Fi with an appropriate tablet/computer, used as an
iGate, as well as “black boxed” with a radio for the hilltop
where it can be just switched on and left by someone without
any ARPS / computer knowledge.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Units that would reliably handle 9600 would
also be useful. Again 25 years ago that was a problem, but
radios from the “big three” (and I think some others) have the
appropriate connections.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So, any recommendations / thoughts?<o:p></o:p></p>
